TimeMachinePerspective... Running out of space on your Time Machine drive? Try this tool.

This is a version of GrandPerspective tweaked so that if applied to a Time Machine drive, it treats any file with outstanding hard links as having zero size.

This is useful for looking at your TimeMachine backups and seeing what files you might want to exclude from the Time Machine backup, because the file is constantly changing. For instance, lets say you have a 10GB database file that changes by 1K every hour. Time Machine will have to back up the entire file everytime, just

That looks like a useful extension of GrandPerspective. Adding support for Time Machine drives has been on my To Do list for a while, as I already imagined that GrandPerspective in its current form does not cope well with Time Machine. However, as I don't have access yet to a machine with Leopard/Time Machine, I have not yet been able to do so. So, thanks for filling the void in the meantime.

Cheers,
Erwin

Let me be a little more specific about my problem (in case the author reads this and wants to respond). This is based on GrandPerspective, a program that graphically represents disk usage. But disk usage doesn't directly equate with file/folder change, which is what causes a Time Machine update. So it doesn't immediately help me spot the kind of files/folders that I need to be excluding from TM updates in order to keep it from eating up excessive disk space. At best it might give me a couple of broad hints, but it puts all the responsibility for identifying such items exclusively on me. I think what we really need, if somebody could write one, is an application that would somehow intercept the backup process in order to create a verbose log that would let me see exactly what is getting uploaded (or that would modify TM so that I could select the files/folders that I DO want to have backed up rather than excluding the ones that I DON'T).

The premise of this software is a great one. Yes, Time Machine is a space-hog because it backs up EVERYTHING including a bunch of stuff like caches that no sane user would want to archive. But the way this is implemented leaves a lot to be desired: the interface may be good-looking, if your taste runs that way, but the poor user is given no help in deciphering or interpreting the data it produces, and that's whole point of interface design, right? If the developer can't or doesn't want to give us an interface that's easier to decipher, he at least owes us some kind of documentation to help us make more sense out of the present one. I'd love a program like this and would enthusiastically give it five stars across the board (or even - gulp - pay money for it) if I could figure out how to put it to good use in managing Time Machine. But I need some help here.

Sounds pretty interesting and useful. Unfortunately it is not working for me as it is promoted.
I'm using Leopard with the latest updates. TimeMachine is storing the backups on a HFS+Journaled FireWire HDD.
With the modified version from GrandPerspective I get exactly the same results as with the original version (0.9.11). Both are telling me 3.17 TB is stored on the 320 GB HDD when "file size measure" is set to Physical. If the "file size measure" is set to Logical then the modified version only reports 22.6 GB but in fact the TimeMachine HDD is filled to 230.1 GB.

TimeMachinePerspective... Running out of space on your Time Machine drive? Try this tool.

This is a version of GrandPerspective tweaked so that if applied to a Time Machine drive, it treats any file with outstanding hard links as having zero size.

This is useful for looking at your TimeMachine backups and seeing what files you might want to exclude from the Time Machine backup, because the file is constantly changing. For instance, lets say you have a 10GB database file that changes by 1K every hour. Time Machine will have to back up the entire file everytime, just because 1K changed. So that's 240GB over a 24 hour period.

When I used it today, I found out that /var/db/RemoteManagement/caches/ was backing up a 6GB filesystem.cache file each backup! So I added /var/db/RemoteManagement to my exclude list in TimeMachine. You can see that in the enclosed screenshot, all the orange squares above are that giant file.

Note: I didn't write the tool, Erwin Bonsma did, and since he made it open source, I just tweaked it.
